Scott,
Pipes works great on OSX and widen quite a bit the interactions between LV
and OSX.
Also using the System Exec.vi you can easily send applescript using
"osascript -e 'your applescript'"
If you need to run in sudo mode try this in 'System Exec.vi' to show a
dialog box to enter your admin pw.
osascript -e 'do shell script "sudo ls" with administrator privileges'
Hope this help
Chris
